Dust suction hose is an indispensable equipment in industrial production to ensure that related operations can run in an orderly manner. According to different working conditions, it can generally be divided into air, ventilation, suction and transportation, dust collection, and anti-static extraction soft Tube and so on. But nowadays, there are more and more vacuum hoses on the market, the quality is uneven. PU steel wire hoses are imported and domestic PU pipes. Both imported and domestic PU steel wire hoses are a kind of wear-resistant hoses made of polyurethane material with steel wires. Many imported equipment use them. It is the original imported pipe. When the pipe is worn out and needs to be replaced, the imported PU steel wire hose often cannot keep up with the delivery time or the price is very high. Many customers will want to know what is the imported PU steel wire hose and the domestic PU steel wire hose. Difference, can it be used instead?
  The common features of imported PU steel wire hose and domestic PU steel wire hose:
   Both imported and domestic PU steel wire suction hoses are TPU hoses with embedded steel wire skeletons. The products are light in weight, soft, good elasticity, corrosion resistance, hydrolysis resistance, high transparency, non-toxic and tasteless, and small bending radius. It has good resistance to negative pressure and can maintain its original shape under vacuum. It can maintain good flexibility at extremely low temperatures. It has super high strength and super long service life.
  Temperature range: about -40℃ to +120℃, up to 150℃ in a short time. With high-adhesion steel wire spiral reinforcement, the inner wall is smooth to ensure the smooth flow of materials in the pipe. Resistant to mineral oil and chemicals. It has excellent ozone resistance and weather resistance, and can still maintain good softness at low temperatures. It does not contain halogen, meets the requirements of RoSH environmental protection directive, and the raw materials meet the requirements of REACH. Compared with traditional rubber hoses and PVC hoses, it has extremely high abrasion resistance and service life. Flame-retardant requirements meet; UL94-HB standard, in line with ROHS regulations, grounding through spiral wire can discharge static electricity.

  The difference between imported and domestic PU steel wire hose:
   1. Many imported PU steel wire hoses use rubber-coated steel wire, and domestically-made PU steel wire hoses use copper-plated steel wire.
  2. Imported hoses are all coded, but domestic PU hoses are rarely coded.
   Generally speaking, domestic PU steel wire hose can completely replace imported PU steel wire hose. However, many domestic manufacturers use low-quality polyurethane raw materials to produce, so the quality is better than imported PU. The hose is bad. Many domestic manufacturers use raw materials worth more than a dozen yuan per kilogram, while imported hoses use raw materials worth 40-50 yuan per kilogram. Then, even if they can be used instead, the service life of the two will be very different. Of course, Buying high-quality domestic PU steel wire hoses can be used instead. For example, the PU steel wire hoses produced by Hangzhou Haikuo use high-quality polyurethane TPU materials imported from the United States, and the quality is completely comparable to imported PU hoses. Moreover, the cost is only one-third of the imported hoses, and the supply is quite sufficient. Basically, the common specifications on the market are available in stock, which not only saves costs, but also saves delivery time.
